In our daily lives, we make a wide variety of decisions. One major distinction that has been made is between perceptual decisions and value-based (economic) decisions. We argue that this distinction is ill-defined, because these decisions vary on multiple dimensions. We present an alternative way to categorize decisions, based on two dimensions: subjective versus objective criteria, and evaluation of a stimulus versus a representation. We experimentally study the decision-making process (with eye-tracking) in each of the four resulting categories, using the same stimulus set of food images. Using a combination of individual-level and group-level modeling, we find surprisingly consistent patterns of behavior across the categories. However, we find stronger similarities between the subjective and objective categories, and stronger differences between the stimulus and representation categories.

心理表征将基于价值的决策与感知决策区分开来

在日常生活中,我们会做出各种各样的决定。已经做出的一项主要区别是感知决策和基于价值的(经济)决策。我们认为这种区别是不明确的,因为这些决定在多个维度上有所不同。我们提出了一种基于两个维度对决策进行分类的替代方法:主观与客观标准,以及刺激与表征的评估。我们使用相同的刺激食物图像集,通过实验研究四个结果类别中的每一个类别的决策过程(使用眼动追踪)。结合个人层面和群体层面的建模,我们发现了跨类别的惊人一致的行为模式。然而,我们发现主观和客观类别之间有更强的相似性,
